Well, to start off this subforum we could go with one of the things players might struggle more with; unlock tokens. The idea is that everyone suggests the ways they did it or think that could be archieved, and anything about them, for it to then be edited in the OP to eventually have an accesible guide for anyone! General guidelines would also be welcome

I'll try starting with the structure (wip as well) and some simple ones:

Get Over HereKill an enemy by pulling it into yourself with the Zenith Guard squad

Field PromotionHave a Pilot reach maximum level

Watery GraveDrown 3 enemies in water in a single battle with the Rift Walkers squad

UntouchableFinish a Corporate Island without taking Mech Damage (Repaired damage is still damage)

Stormy WeatherDeal 12 damage with Electric Smoke in a single battle with the Rusting Hulks squad

- A good method to get this one is to do so with the upgrade to Electric Smoke increasing its damage by +1, and apply it in a battle full of weak enemies. For me, the best place to do this is in the bossfight with the "Goo", as it'll divide several times into weaker and weaker versions of itself that are semi mandatory to kill in the mission objective and are well dealt with Smoke, as well as some of the other Vek in the fight.

Perfect BattleTake no Mech or Building Damage in a single battle with the Rusting Hulks squad (Repaired damage is still damage)

OverpoweredOverpower your Power Grid twice by earning or buying Power when it is full with the Rusting Hulks squad

- The two points of overpowering do not need to be consecutive, so don't be afraid of risking a hit if you'll get it back later. It's pretty easy to get it in a sweep at the first Island's store if you spend all your reputation in more power and have gone for missions awarding it.

This is FineHave 5 enemies on Fire simultaneously with the Flame Behemoths squad

Shield MasteryBlock damage with a Shield 4 times in a single battle with the Zenith Guard squad

Cryo ExpertShoot the Cryo-Launcher 4 times in a single battle with the Frozen Titans squad

Hold the LineBlock 4 emerging Vek in a single turn with the Blitzkrieg squad

- Most likely you'll need to use the Boulder Mech's rock, which can serve as a static blocker added to the rest of your squad.

HealingHeal 10 Mech Health in a single battle with the Hazardous Mechs squad

Class SpecialistBeat the game with 3 different Mechs from the same class in a Custom squad

Backup BatteriesEarn or buy 10 Grid Power on a single Corporate Island- (Treamayne) Go for this when you see you can tackle five regions that all provide power, then you may only need to buy 1-3 power with reputation.

Good SamaritanEarn 9 Reputation from missions on a single Corporate Island- (Treamayne) Go for this when you see you can get at least 7 reputation in your five missions (since the boss fight will always be for 2 rep at the end of the island)

Pilot Challenges

Field PromotionHave a Pilot reach maximum level

Best of the BestHave 3 Pilots at maximum level simultaneously

Come TogetherUnlock 6 additional Pilots

I'm getting too old for this...Have an individual Pilot fight the final battle 3 times across multiple games- (Treamayne) Just make sure you keep returning the same pilot every game (abandon the timeline if the pilot might die) until you unlock this achievement- (Treamayne) [suggestion] To make this "more difficult," the achievement should require going to the Final Battle with a single pilot three times in a row

Distant FriendsEncounter a familiar face- (Treamayne) Received with Custom Squad, third Island, First Mission, after the last turn when I clicked "End Turn"- (Treamayne) Watch for something different in a mountain that has been hit once

Engineering DropoutFinish 3 Corporate Islands without powering a Weapon Modification- (Treamayne) Custom Squad is great for this, as you can choose three mechs with strong enough main abilities that you can get through the first three islands without the modification (avoid mechs like Lightning Mech, that really really want that first mod to be effective). Any squad with Nano Mech stands a good chance at this.

ChronophobiaFinish 3 Corporate Islands and destroy every Time Pod discovered- (Treamayne) Slightly harder than it seems, since only your deliberate action can destroy a time pod. Using a squad with some "push" abilities helps, since you can push a Vek onto the tile to destroy the pod- (Treamayne) Avoid "high instance" time pod regions (Defend Train, Defend Refield Bombs, Destroy Dam). If yo usee less pods, it's easier to destroy "all you encounter"

There is No TryFinish 3 Corporate Islands without failing an objective- (Treamayne) Avoid "block spawning" regions, as that seems (to me) the easiest objective to fail. RNG loves to get you fighting on one side, then put a spawn outside of everybody's movement range.

Trusted EquipmentFinish 3 Corporate Islands without equipping any new Pilots or weapons- (Treamayne) Try to do this at the same time as you go for "Chronophobia," since you will have less chance at pilots and weapons anyway.- (Treamayne) Custom Squad using mechs with good modifications (like Lightning Mech) make it easier to not need new weapons.

Squad Based:

Rift Walkers

Watery GraveDrown 3 enemies in water in a single battle with the Rift Walkers squad

Ramming SpeedKill an enemy 5 or more tiles away with a Dash Punch with the Rift Walkers squad

OverpoweredOverpower your Power Grid twice by earning or buying Power when it is full with the Rusting Hulks squad- (Arnust) The two points of overpowering do not need to be consecutive, so don't be afraid of risking a hit if you'll get it back later. It's pretty easy to get it in a sweep at the first Island's store if you spend all your reputation in more power and have gone for missions awarding it.- (Treamayne) Go to Archive first, and when you see a chance to have every mission award at least 1 power - you can fairly easily get this achievement as the first two regions will get you to full power and you only need to get the bonus power from two of the remaining three attempts.

Stormy WeatherDeal 12 damage with Electric Smoke in a single battle with the Rusting Hulks squad- (Arnust) A good method to get this one is to do so with the upgrade to Electric Smoke increasing its damage by +1, and apply it in a battle full of weak enemies. For me, the best place to do this is in the bossfight with the "Goo", as it'll divide several times into weaker and weaker versions of itself that are semi mandatory to kill in the mission objective and are well dealt with Smoke, as well as some of the other Vek in the fight.- (Treamayne) If you see a chance to buy (or luckily get from a pod/island bonus) the Smoke Pellets (for your Pulse Mech), take them. It makes this achievement much easier.

Perfect BattleTake no Mech or Building Damage in a single battle with the Rusting Hulks squad (Repaired damage is still damage)

Zenith Guard

Get Over HereKill an enemy by pulling it into yourself with the Zenith Guard squad

Glittering C-BeamHit 4 enemies with a single laser with the Zenith Guard squad

Shield MasteryBlock damage with a Shield 4 times in a single battle with the Zenith Guard squad- (Treamayne) You will need the "+1 use" upgrade. At the start, put your Laser and Charge mechs next to each other, with the Defense mech at least 1 square away (in line) and use your first action to drop a shield on the Laser and Charge Mechs. They will invariably bump or get hit (you can block a spawn if needed to "use" the shield) and that is half the work. You may even get the chance to use your second shot on the mechs again.

Blitzkrieg

Chain AttackHave the Chain Whip attack chain through 10 Tiles with the Blitzkrieg squad- (Treamayne) This is almost inevitable if you are going for the 4 island victory. Once there are enough enemies on a congested map, just look for the opportunity to move a mech and connect groups into a large chain.

Lightning WarFinish the first 2 Corporate Islands in under 30 minutes with the Blitzkrieg squad- (Treamayne) Avoid unnecessary actions (don't move or repair if you don't have to) and try for "Block Spawning" missions, as the more enemies you block, the less fighting you do and the more time you save.Also, avoid using R.S.T. in your first two islands. There are too many regions with environmental effects that waste a lot of time when trying to earn this achievement.

Hold the LineBlock 4 emerging Vek in a single turn with the Blitzkrieg squad- (Arnust) Most likely you'll need to use the Boulder Mech's rock, which can serve as a static blocker added to the rest of your squad.- (Treamayne) One thing to remember about this, is you will likley need to block two spawns in one round to have 4 available to block on the round after it. You can also, sometimes, push a Vek over one of the spawn tiles if Boulder Mech is too far away to move there itself.

Steel Judoka

UnbreakableHave Mech Armor absorb 5 damage in a single battle with the Steel Judoka squad- (Treamayne) Use Abe Isamu so you have two mechs with armor, and this becomes much easier to earn.

Unwitting AlliesHave 4 enemies die from enemy fire in a single battle with the Steel Judoka squad

Mass DisplacementPush 3 enemies with a single attack with the Steel Judoka squad- (Treamayne) Siege Mech is the face of this achivement, but don;t be shy about using Judo Mech and/or Gravity Mech to get at least three enemeis around a single point for Siege Mech to push them all. Great on islands with Blobber or Spider (Spider Leader), since you can push the thrown blobs too.

Scorched EarthEnd a battle with 12 tiles on Fire with the Flame Behemoths squad

This is FineHave 5 enemies on Fire simultaneously with the Flame Behemoths squad

Frozen Titans

Cryo ExpertShoot the Cryo-Launcher 4 times in a single battle with the Frozen Titans squad

Trick ShotKill 3 enemies with a single attack of the Janus Cannon with the Frozen Titans squad

PacifistKill less than 3 enemies in a single battle with the Frozen Titans squad

Hazardous Mechs

HealingHeal 10 Mech Health in a single battle with the Hazardous Mechs squad

ImmortalFinish 4 Corporate Islands without a Mech being destroyed at the end of a battle with the Hazardous Mechs squad

OverkillDeal 8 damage to a unit with a single attack with the Hazardous Mechs squad

Randomized Squad

Loot Boxes!Open 5 Time Pods in a single game with a Random squad

Lucky StartBeat the game (any length) without spending any Reputation with a Random squad- (Treamayne) If possible, use special pilot to shore up any science or other non-damage mechs. Decide to play for this if you get two time-pods on the first island (since you won;t be buying upgrades) and if needed, use the +2 energy perfect island bonus to keep your grid high.

Change the OddsRaise Grid Defense to 30% or more with a Random squad

Customized Squad

Mech SpecialistBeat the game with 3 of the same Mech in a Custom squad- (Treamayne) It's a challenging run, but 3x Jet Mech can get the Mech and Flight Specialist achievements at the same time.

Class SpecialistBeat the game with 3 different Mechs from the same class in a Custom squad

Flight SpecialistBeat the game with 3 flying Mechs in a Custom squad- (Treamayne) Prospero won't count as flying in a normal mech, even with his flight activated.- (Treamayne) It's a challenging run, but 3x Jet Mech can get the Mech and Flight Specialist achievements at the same time.
